Sulphur Dyes
Sulphur dyes are a broad class of inexpensive, water-insoluble colorants for cellulosic fibers that are applied in solubilized leuco form from an alkaline sodium sulfide reducing bath, exhaust onto cotton at moderate temperatures, and are then re-oxidized within the fiber to form their insoluble colored structure. Available across a full color range including blacks, navies, browns, khakis, and olive greens, sulphur dyes offer excellent washing fastness and good light fastness at very low cost, making them the preferred choice for commodity dyeing of cotton yarn, woven fabric, and knitwear where shade reproducibility and economy are priorities. The range includes pre-reduced liquid sulfur dyes that eliminate sodium sulfide handling and reduce effluent BOD.
Key Applications
- Cost-effective exhaust dyeing of cotton yarn packages and beam
- Continuous pad-steam dyeing of woven cotton in navy, brown, and khaki
- Knitted fabric dyeing in commodity fashion and workwear shades
- Yarn dyeing for woven shirting and bottomweight fabric production
Frequently Bought Together
Direct Dyes
Direct dyes are anionic water-soluble azo and stilbene colorants that exhaust directly onto cellulosic fibers from a neutral or weakly alkaline electrolyte bath without the need for chemical fixation auxiliaries, making them among the simplest and most cost-effective dye classes for cotton, viscose, and linen in commodity shades across a full color range.
Textile Dyes & AuxiliariesIndigo Blue
Indigo Blue is the iconic vat dye responsible for the distinctive blue color of denim fabric, applied to cotton warp yarns by continuous rope or slasher dyeing using a sodium hydrosulfite reducing bath followed by air oxidation in multiple dip-nip cycles to build up the characteristic surface-dyeing that produces the ring-dyeing effect essential to authentic denim fading behavior.
Textile Dyes & AuxiliariesBasic Dyes
Basic dyes (cationic dyes) are highly brilliant, intensely colored ionic colorants with strong affinity for acrylic, modacrylic, and paper fibers, and secondary affinity for mordanted wool and silk, providing saturated fluorescent-level hues in red, blue, yellow, green, and violet that cannot be achieved with any other dye class.
